Description

TECHNICAL FIELD

The present disclosure relates to the field of washing of washing machines, and particularly relates to a detergent dispensing control method, a washing machine and a system.

BACKGROUND

When a washing machine is used for washing clothes, a detergent needs to be added. At present, there are two methods for adding the detergent: 1) the detergent is manually added; and 2) a detergent dispensing device is arranged on the washing machine, the detergent is added into a detergent box in advance, and the detergent dispensing device can be controlled to automatically dispense the detergent when the washing machine executes washing.
However, the amount of clothes to be washed by a user each time is different, clothes to be washed each time are different, if the user wants to obtain the optimal washing effect, aiming at different weights and materials of clothes, the detergent dispensing amounts are different. But detergents sold in the market have various categories, for the clothes with the same weight and the same material, the detergents dispensing amounts are different according to different categories of detergents. Therefore, how to obtain an accurate detergent dispensing amount is an important factor for a clothes washing effect.
